No. 15/533,873, filed Jun. 7, 2017, which is the U.S. National Phase of International Application PCT/CN2015/096777, filed Dec. 9, 2015, which claims priority and interest of China Patent Application No. 201410749394.0 filed with the China National Intellectual Property Office on Dec. 9, 2014. The disclosures of each of the foregoing applications are hereby incorporated by reference in their entireties.

TECHNICAL FIELD

The present application relates to the field of pharmaceutical technology, and the present application relates to the use of quinoline derivatives for antitumor purposes. Specifically, this application relates to the use of quinoline derivative in the treatment of non-small cell lung cancer (e.g., lung adenocarcinoma).

BACKGROUND TECHNIQUE

Cancer is a major public health problem in many parts of the world. Among them, lung cancer due to morbidity and mortality are high, becomes the whole one of the major causes of cancer death in the world, for non-small cell lung cancer (NSCLC), although platinum-containing chemotherapy can change the survival of advanced patients, but the prognosis of advanced non-small cell lung cancer is still very poor and 5-year survival rate is less than 10%. It is reported that further study of tumorigenesis and chemical resistance in lung cancer is required in order to increase survival (Jemal A et al., Cancer Statistics, CA Cancer. J. Clin., 56, 106-130, 2006). Based on cell morphology, adenocarcinoma is a common NSCLC group (Travis et al., Lung Cancer Principles and Practice, Lippincott-Raven, N.Y., 361-395, 1996). NSCLC's first-line chemotherapeutic regimen usually contains platinum-containing drugs, which points to that platinum-based drugs (cisplatin or carboplatin) are added with a second chemotherapeutic agent (Pacific paclitaxel, pemetrexed, gemcitabine, Vinorelbine, etc.) (Dadario et al., 2010; National Comprehensive Cancer Network Oncology Clinical Practice Guide, Non-small cell lung cancer, 2010 second edition). For the advanced non-small cell lung cancer, especially lung adenocarcinoma, although the driving gene targeted therapy has obtained a certain clinical efficacy, in the end there will be resistance which results in disease progression, and the treatment of lung adenocarcinoma with non-driven genes is still based on platinum-based chemotherapy. Therefore, non-small cell lung cancer and histological type of lung adenocarcinoma, still need to develop more drugs, in order to achieve better treatment, improve survival, to bring substantial benefits to patients.

Previous bronchial brush biopsyshowed non-small cell carcinoma, with high probability of adenocarcinoma, combined with imaging findings, achieved the clinical diagnosis: left upper lobe lung adenocarcinoma, bilateral lung metastasis, mediastinal lymph node metastasis, bilateral supraclavicular lymph node metastasis (T4N3M1a, stage IV), accompanied by multiple lacunar infarction, pericardial effusion, cholangiolithiasis and other diseases. From Aug. 1, 2013 to Sep. 1, 2013, a treatment cycle of TP regimen (paclitaxel/cisplatin) was given, while the outcome was unsatisfactory, chemotherapy regimen was changed subsequently. From Dec. 26, 2013 to Jan. 15, 2014, the GP regimen (gemcitabine/cisplatin) was given for one treatment cycle still with unsatisfactory outcome. On Jan. 20, 2014, Icotinib Hydrochloride Tablets 125 mg p.o. tid. were given with unknown outcome. On Feb. 27, 2014, CT scan showed that the several lesions existed in parts of body including bilateral lung, hilum of left lung lymph node, bilateral supraclavicular lymph node, and mediastinal lymph node, in which the longest diameter of the lesion in anterior segment of the left upper lobe lung was 37 mm, and the shortest diameter of the lesion in mediastinal lymph node was 21 mm Tumor marker tests showed that the level of CEA was up to 107.41 ng/mL, which is not within the normal range.

From Feb. 28, 2014, the capsule of dihydrochloride of compound I was taken orally at 12 mg once daily with repeated treatment cycles (treatment given for consecutive two weeks followed by one week of rest is one treatment cycle).

B) CT Scan Results

After treatment with dihydrochloride of compound I, the sum of the longest diameter of the target lesions reduced considerably. Before undergoing the therapy, the sum of the diameter of two measurable target lesions was 58 mm (the anterior segment of left upper lobe lung 37 mm, the mediastinal lymph node 21 mm), and reduced to 36 mm after three-week admistration, i.e., reduced by 37.9% (the anterior segment of left upper lobe lung 18 mm, the mediastinal lymph node 18 mm); then reduced to 29 mm when administration was given for six weeks, i.e., reduced by 50% (the anterior segment of left upper lobe lung 14 mm, the mediastinal lymph node 15 mm); and reduced to 26 mm after nine-week administration, i.e., reduced by 55.2% (anterior segment of left upper lobe lung 10 mm, the mediastinal lymph node 16 mm); then remained 26 mm when administration was given for twelve weeks, i.e., reduced by 55.2% (anterior segment of left upper lobe lung 10 mm and the mediastinal lymph node 16 mm); and reduced to 25 mm, i.e., reduced by 56.9% after 15-week administration (anterior segment of left upper lobe lung 10 mm, the mediastinal lymph node lesions 15 mm). progression of non-target lesions and new lesions were not observed. Until Dec. 4, 2014, dihydrochloride of compound I had been given for 279 days, and the treatment continued during the 14th treatment cycle, while sustained response against tumor and good clinical performance of the therapy was observed.

C) Tolerance

Treatment with dihydrochloride of compound I was generally well tolerated. Blood changes were not significant. There was no heart toxicity related to the drug during treatment.

Example 7

On Jun. 2, 2014, a 62-year-old female patient was found left lung cancer, lung metastasis, double hilar and mediastinum, right supraclavicular lymph node metastasis by CT examination, and ECT suggested bone metastases, cranial MRI suggested left frontal lobe transfer. She was diagnosed as non-small cell lung cancer by CT-guided lung puncture. EML4-ALK fusion gene had no mutation, EGFR gene had no mutation by gene detection.

From Jun. 9, 2014 to Sep. 25, 2014, the patient was treated with cisplatin and pemetrexed chemotherapy for 6 cycles, and the best efficacy was PR. During the treatment the patient had II degree gastrointestinal reactions, no bone marrow suppression. From Oct. 17, 2014 to Nov. 1, 2014 at the time of discharge, the patient was treated with Ti guio capsules for 2 weeks, and had cough relief, mild chest tightness. On Jan. 27, 2015 disease was found progression by check. From Jan. 31, 2015 to Jun. 21, 2015, the patient was treated with Icotinib combined with docetaxel chemotherapy for 6 cycles, and the best efficacy was SD. On Jul. 8, 2015, the patient participated in the clinical study of dihydrochloride of compound I capsules, and the same day began the dihydrochloride of compound I capsule treatment that one cycle plan was 12 mg dose once, q.d., and continuous medication for 2 weeks, and then suspended medication for 1 week.

On Jul. 29, 2015 patients received treatment for 1 cycle, and enhanced CT suggested left upper lobe of the lung with obstructive inflammation, double lung shift, the gap between the lower lobe of the lungs thickening, left hilar and mediastinal lymph node metastasis, right supraclavicular lymph nodes, and the double lateral pleural metastasis was likely, and part turned better, and part didn't change significantly. Evaluation of the best efficacy has reached PR according to RECIST1.1.

On Aug. 20, 2015 Patients' head enhancement CT suggested that the left temporal lobe nodules were slightly smaller than baseline.

On Nov. 12, 2015 enhanced CT suggested that the condition has been controlled, and the efficacy was still PR. Until application date, the patient could tolerate adverse reactions and continued to receive treatment.

Example 8

March 2013, a 62-year-old male was diagnosed as non-small cell lung cancer squamous cell carcinoma by CT-guided lung puncture and cranial MRI suggested left frontal lobe transfer. EML4-ALK fusion gene had no mutation, EGFR gene had no mutation by gene detection.

From Mar. 26, 2013 to Jun. 5, 2013, the patient was treated with cisplatin and gemcitabine chemotherapy for 4 cycles, and the best efficacy was SD. After the end of the chemotherapy, he was treated with the local radiotherapy of the lung for 1 cycle, during which the adverse reactions was light. From Sep. 9, 2013 to Oct. 6, 2013, the patient was treated with cisplatin and gemcitabine chemotherapy for 2 cycles. December 2013, disease was found progression by review of CT. From Mar. 24, 2014, the patient was treated with docetaxel chemotherapy for 1 cycle. After chemotherapy, bone marrow suppression, oral infection, pneumonia appered, and the condition improved after symptomatic treatment. On Dec. 10, 2014, review CT suggested that: 1 Right upper hind plate soft tissue shadow increased than before; 2. Double lungs had multiple pulmonary bullae, which changed little than before; 3. Double lungs had inflammation, the scope of which was smaller than before; 4. Left clavicle, mediastinal and right hilar had multiple lymph nodes, which were slightly larger than before. From Jan. 7, 2015 to Jan. 29, 2015, Gemcitabine and nedaplatin (NDP) were given and grade III bone marrow suppression appeared after chemotherapy, which recovered after Rise white was given. On Mar. 4, 2015 review CT suggested that right lung mass increased than before. On Mar. 6, 2015, the patient was treated with oral Tiggio treatment. On May 27, 2015 Review CT suggested progress. On Jun. 2, 2015 pathology diagnosis suggested (right lung) poorly differentiated carcinoma after right lung squamous cell carcinoma radiotherapy and chemotherapy.

From Jun. 4, 2015, the patient received dihydrochloride of compound I capsule treatment that one cycle plan was 12 mg dose once, q.d., and continuous medication for 2 weeks, and then suspended medication for 1 week. On Jun. 25, 2015 patient was treated for 1 cycle, and enhanced CT suggested right hilar soft tissue density lumps, which were slightly smaller than berore; Left clavicle, mediastinal and right hilar had multiple lymph nodes; Double lungs had inflammation, which changed little than before; Double lungs had multiple pulmonary bullae, which changed little than before; Evaluation of efficacy has reached SD according to RECIST1.1, and the total target lesions was 66 mm, which was redused by 10 mm than the baseline

On Jul. 15, 2015 patient's enhanced CT suggested right hilar soft tissue density lumps, which were slightly smaller than before. Target lesion sum was 63 mm; On Sep. 8, 2015, enhanced CT suggested lesions were further redused, and target lesion sum was 57 mm; On Oct. 16, 2015 enhanced CT suggested lesions were reduced, the target lesion sum was 56 mm, which changed little than before; Until application date, the patient could tolerate adverse reactions and continued to receive treatment.
